Where the two Invidia N1 styles differ is their midpipe. The 'Street' midpipe features a flex joint for easy installation as well as an inline resonator giving this system an aggressive yet deep and subtle touring style tone, suited better for daily driven street cars. The ravenous Invidia N1 'Race' exhaust features the same 76mm (3 inch) mandrel bent stainless steel piping but does not have a resonator or flex section. The result is a much louder, race car exhaust tone that will scream at wide open throttle. All Invidia N1 exhaust systems for the 08-10 STI include necessary hardware and gaskets for installation. N1 Exhaust systems vary depending on body style, please choose accordingly below.
Note: Are you using a stock j pipe or downpipe? If yes, the GrimmSpeed Subaru Stock DP to Aftermarket 3 in. Catback Adapter p/n 077046, is required.
Invidia has great quality and awesome sound.
Sounds great. Good price. Looks good on the car too.
Called up and got some great advice on comparing my options on exhausts and he was the only one with some N1’s in stock. Needless to say have been enjoying it ever since. Thanks iir
